This is absolute TOPS for sheer aesthetic quality for this material because it has large sharp crystals well-isolated on matrix . The crystals are just perfect, with a gorgeous purple-green translucency, and are perfectly balanced on the contrasting white matrix. The specimen is crowned with a superb crystal of over 3 cm on edge that “tops it off” perfectly . These are best shown in sunlight or with backlighting coming through from behind, or they do look dark; but when displayed properly are really neat fluorites. New finds! 13 x 10.5 x 5 cm
Not your average Chinese fluorite, but a KILLER plate of GLASS-CLEAR crystals, measuring to 2.4 cm on edge. You can see right through the crystals to the matrix. The largest crystals ring the top of the specimen, so they are perfectly positioned to be shown off. There are a few very minor dings, MINIMAL for a specimen this size. It''s just a great fluorite! 12.0 x 8.8 x 4.0 cm
We have been leaking out Okarusu fluorites for some time now, but every now and then one comes along that is really different and exceptional, such as this one. The crystals, while not large (to 1.3 cm), are extremely sharp and transparent, so that you can see the matrix right through them. They show the wonderful shades of purple and green that make the Okarusu famous. The crystals have grown on a sculptural matrix that extends up to the left and right, and bits of quartz add an extra accent. The two "branches" rise from a flat matrix "base", so the specimen does not even need a stand. This piece is actually much prettier in person than the photos . . .an absolute smoker. 9.0 x 6.8 x 6.4 cm
Crystals to 1.5 cm of the famous teal blue. Very minor damage. 5.6 x 3.1 x 2.9 cm
The crystal in the center here measures 4 CENTIMETERS along the front edge! These crystals have good transparency and nice deep pink color. A fine and large one! 11.5 x 7.8 x 3.5 cm
Three crystals, complete in front (contacts in back where removed from matrix), showing superb sharpness and delicate purple edges around a creamy center. The largest crystal measures over 4 cm. A floater crystal of sphalerite is embedded in the lower-most fluorite! 8.1 x 5.0 x 5.0 cm
A pink fluorite crystal strangely distorted by having grown around crystallized galena. In two places where it has grown around the side of the galena, you can see it trying to form octahedrons, with a few sharp faces fully formed! 5.0 x 4.2 x 2.8 cm
This English fluorite specimen came with an index card from 1955 indicating that it was obtained in a swap with the American Museum of Natural Histor (David Seaman). The crystals, many of them gemmy, measure to about one centimeter, and show wonderful purple color. Siderite has grown on one side of the specimen, and is interspersed with some of the fluorites on the display face as well. Hey, you can tell people you own something that was in the Smithsonian! 10.4 x 6.2 x 6.0 cm (NOTE: The locality is wrong. Colour and association strongly hint to Weardale)
Auglaize fluorites are of course uncommon on the market, and are extremely distinctive amongst fluorites due to their extremely high luster, something you don''t see in fluorites from any other locality. They little cubes here look like small purple gems, filling two recesses in the matrix (and a third small one). 6.5 x 4.9 x 4.5 cm
3.2 x 2.8 x 1.2 cm (largest). A fine and very representative suite of Fluorites from the Erongo Mountains. The largest of Fluorites is 3 cm across. The greens run from a lime green to a forest green, and many of the crystals have also a classic purple edging that Erongo is known for. One of the crystals is even the smaller cousin to the extraordinary "alien" Fluorites that came out in 2008 and were the sensation at this year’s Tucson Show (2009). The golden Fluorite in this suite is wrapped around a very sharp Quartz crystal, and is penetrated by several Schorl crystals. Ex. Charlie Key Collection.
14.7 x 10.3 x 7.6 cm. This is a large specimen showing off sharp calcite crystals that have been completely replaced by fluorite. It is sparkly and pretty, and has rich hues of purples to hematite-stained reds. It is an impressive and an unusual pseudomorph. Weighs 880 grams.
2.1 x 2.0 x 0.9 cm. The Sweet Home mine is famous for its Rhodochrosite specimens, and Richard Kosnar mined the Sweet Home for a few years during the late 1970's and managed to collect some excellent Rhodochrosite specimens. It features a few sharp, translucent, reddish-pink Rhodochrosite rhombohedra perched atop white "needle" Quartz and associated with minor sulfides. The final touch to this specimen is a small, sharp, gem quality dodecahedron of lavender Fluorite at the base. This piece is from one of the early pockets that Rich Kosnar opened when he started mining in 1977. Ex. Richard Kosnar Collection.
4.9 x 4.5 x 3.0 cm. A classic, beautiful fluorite specimen from the Minerva #1 Mine of Illinois. The glassy, transparent cubes have striking yellow cores with purple color zoning on the outer part of the stepped-faced crystals. Ex. Consie Prince Collection.
9.2 x 6.9 x 4.1 cm. A fine, 3-dimensional specimen from the famous, but less well-known Deardorff Mine of the Illinois Fluorspar District. Well-placed and isolated sphalerite and fluorite crystals are set like jewels on the coral-like, drusy quartz matrix. The 1.3 cm, fuchsia, fluorite cube and 1.7 cm lustrous, twinned, jet-black sphalerite are stunning in their crestal locations. Smaller sphalerite and fluorite "jewels" are nestled in the drusy quartz framework. This is classic, old-time material from this mine dating from the 1930s to 1950s, as the mine closed in the early 1960s. The Deardorff was considered to be the specimen mine of this period in Southern Illinois.
20.0 x 14.0 x 7.0 cm. Gem-like, blocky to tabular, golden-amber baryte crystals to 1.5 are studded on the massive green fluorite matrix with a sparkling multitude of smaller baryte crystals on this dramatic and impressive large cabinet specimen from finds in China a couple of years ago.
